摘要：

In this comment to S. Lenjer, O. F. Schirmer, H. Hesse, and Th. W. Kool, Phys. Rev. B 66, 165106 (2002), we discuss the electronic structure of oxygen vacancies in perovskites. First-principles computations are in favor of rather deep levels in these vacancies, and Lenjer even suggest that the electrons' interaction energy is negative. However, data on electroconductivity are against both these scenarios.
